Summary: NPE in ThrowableProxy when resolving stack
Key: LOG4J2-1687
URL: https://issues.apache.org/jira/browse/LOG4J2-1687
Project: Log4j 2
Issue Type: Bug
Components: Core
Affects Versions: 2.7
Environment: - java version "1.7.0_80" ,Java(TM) SE Runtime
Environment (build 1.7.0_80-b15), Java HotSpot(TM) 64-Bit Server VM (build
24.80-b11, mixed mode)
- Jboss EAP 5.2.0-EAP
Reporter: Robert Christiansen
NPE when logging in Java EE/OSGi environment.
In some cases the ClassLoader (
https://docs.oracle.com/javase/7/docs/api/java/lang/Class.html#getClassLoader()
) will be null for a Class.
With the changes introduced in
https://issues.apache.org/jira/browse/LOG4J2-1457 logging with %xEx can cause a
NullPointerExeception when trying to resolve the stack.
Since it's not a common occurrence in most environments I suggest the
ThrowableProxy swallow the NPE in the same way it swallows SecurityExeception
and other classloading exceptions to avoid extra branching for all environments.
